Description
Technical Field
The invention relates to the technical field of photoelectrocatalysis, in particular to a synthesis method of a novel Z-type heterojunction structure photoelectrocatalysis material.
Background
Photocatalytic degradation is a viable method for removing organic matter from water sources. Due to the advantages of low cost, multiple functions, high efficiency, mild reaction conditions, etc., photocatalysis is increasingly applied to the degradation of organic pollutants.
Researchers have also been working on the design and synthesis of a wide variety of highly efficient photocatalysts that convert inexhaustible solar energy into the driving force for photodegradation. In various heterojunction structures, more active substances are generated because the Z-type heterojunction system retains the stronger reducibility and oxidizability of electrons and holes. These active substances produced (·O2 -、·OH and h+) Can effectively degrade organic substances.
Methyl orange is a commonly used indicator in analytical chemistry. Methyl orange is also an azo dye and can be used for printing and dyeing textiles. The discharge of dye wastewater such as methyl orange and the like can cause visual pollution, when the color of the water body is deepened, sunlight is prevented from irradiating the water body to a great extent, and then the growth of animals and plants in the water is influenced. Meanwhile, the natural decomposition of the organic dye in the environment consumes a large amount of oxygen, and the water body can smell due to oxygen deficiency, thereby further causing the pollution of water resources.

Naturally cooling the high-pressure autoclave to room temperature, taking out the NF sheet, washing with deionized water, and then heating at 80 deg.CDrying in vacuum for 10 h to obtain Ni (OH)2Modified NF (Ni (OH)2/NF) and calcining for 3 hours at 400 ℃ to obtain NF/NiO.
(2) Silver electroplating: and (2) placing the NF/NiO sheet prepared in the step (1) into 3 mL of silver ammonia solution, 2 mL of H2O and 1 mL of electrolyte mixed with KNO3 by adopting a traditional three-electrode system electrochemical deposition method, depositing for 1200 s at minus 0.2V, and finally washing with ultrapure water to obtain the NF/NiO/Au.

The above mixed solution was stirred for 30 min to ensure complete dissolution, and then 20 mL of 6.8 g Ammonium Persulfate (APS) solution was added dropwise as an oxidizing agent to initiate polymerization. During the polymerization, the solution changed from colorless to dark gray, indicating the formation of polypyrrole (Ppy). The mixed solution obtained by the reaction was left at room temperature for 6 hours to complete the polymerization, the obtained precipitate was washed with ultrapure water and then with acetone several times (about 10 times), and the finally obtained PPy/MAA composite material was subsequently dried under vacuum at 60 ℃.
(4) PPy/MAA modified substrate material: the resulting PPy/MAA composite was ground to a powder and sonicated to form a 2 mg/mL homogeneous solution. And (3) uniformly dripping 1 mL of the homogeneous solution on the NF/NiO/Au substrate prepared in the step (2), repeatedly dripping and coating for many times, and drying at 60 ℃ to finally obtain the photoelectric material with the Z-type heterojunction structure of NF/NiO/Au/PPy/MAA.
(5) Application of photoelectrocatalysis: immersing the NF/NiO/Au/PPy/MAA electrode in 60-80 mL of 1 g/L Methyl Orange (MO) solution, and magnetically inducing and stirring the suspension in the dark for 20-30 min to establish the absorption and desorption balance of the dye and the electrode surface under normal atmospheric conditions. And (3) using a xenon lamp as sunlight, irradiating the sunlight by using the xenon lamp to perform photocatalytic degradation reaction, and collecting the mixed solution every 3-6 min. The residual concentration of the dye was determined using a uv-vis spectrometer.
The invention has the beneficial effects that:
(1) the method has the advantages of low cost, simple experimental operation and easily controlled reaction conditions;
(2) the prepared NF-NiO/Ag/MAA-PPy catalytic material has the advantages of wide spectrum absorption range, large specific surface area, high stability and the like.
(3) Compared with the traditional II type heterojunction structure, the Z type heterojunction structure better reserves the oxidation reduction capability of a photoproduction electron hole, so that the catalytic activity is high.
The following is a description of detailed embodiments of the present invention: a method for synthesizing a novel Z-shaped heterojunction structure photoelectric catalytic material.
